   * Creates ReporterManager instances for the providers.

   * A ReporterManager and the underlying reporters are stateful objects. For safe concurrent usage
   * of the reporting infrastructure, each thread needs its own instance.
   * <p/>
   * This factory also ensures that runStarting/runCompleted is called on the FIRST reporterManger that
   * is allocated, but none of the subsequent managers.
